a plot showing the pH of a solution being analyzed as a function of the amount of titrant added
The approximate pH of the equivalence point in a titration pH curve is around 7 for a strong acid-strong base titration. This is because at the equivalence point, the moles of acid are equal to the moles of base, resulting in a neutral solution.
The curve most likely follows a pH profile where the enzyme shows maximum activity at very low pH values (strongly acidic conditions). This would suggest that the enzyme is optimized to function efficiently in the acidic environment of the human stomach.
The titration curve obtained in titration of HCl against NaOH is a typical acid-base titration curve. It shows a gradual increase in pH at the beginning due to the addition of base (NaOH). At the equivalence point, the curve shows a sharp increase in pH since all the HCl has been neutralized. After the equivalence point, the pH continues to rise as excess NaOH is added.
The titration curve of phenylalanine shows the pH changes as a strong acid or base is added to a solution of phenylalanine. At low pH, the carboxyl group is protonated and the amino group is deprotonated. As the pH increases, the carboxyl group loses a proton first, followed by the amino group. The curve typically shows two distinct equivalence points corresponding to the two acidic pKa values of phenylalanine.
The buffer titration curve shows how the pH of a buffer solution changes as acid or base is added. It helps us understand how buffers resist changes in pH by maintaining a relatively stable pH level. This is important in various biological and chemical processes where maintaining a specific pH is crucial for proper functioning.

Stephen curve is a graph plotted on pH level against time. This graph will show that the food intake will reduce pH level in the mouth to a level bad for teeth and then rises again with time.

To calculate the pKa from a titration curve, identify the point on the curve where the concentration of the acid and its conjugate base are equal. This is the half-equivalence point. The pH at this point is equal to the pKa of the acid.
To determine the pKa from a titration curve, identify the point on the curve where the pH is equal to the pKa value. This point represents the halfway point of the buffering region, where the concentration of the acid and its conjugate base are equal.
